UNITED STATES WILLIAM E. GERLACH, OF HUNTINGTON, WEST VIRGINIA.

SAWING MACHINE.

Application led October 1, 1923. Serial No. 665,973.

T all whom t may concern:

Beit known that I, WILLIAM E. GEIILACII, a citizen of the United States, residing at Huntington, in the county of Cabell and State of West Virginia, have invented new and useful Improvements in Sawing Machines, of which thevfollowing is a specifcation.

This invention relates to a sawing machine for cutting the ends of roof boards at the eaves, and for use under other similar conditions.

The object is to provide a device ivhich shall include a frame Inounting a motor, the

frame carrying rollers at its lower end and handles at the upper end, and designed for operation in a manner similar to that of a barrel truck or baggage truck, the motor driving a circular saw positioned to cut the boards to a uniform length after they have been nailed to the roof timbers.

A further object is to provide in such a device a transverse saw shaft, with gearing for driving this shaft from the shaft of 'an air Inotor, or other novel motor carried by the truck.

With the foregoing and other objects in view, the invention consists in the novel construction and arranvement of elements described and claime it being understood that modifications may be made Within the scope of the claim without departing from the spirit of the invention.

The drawing is a perspective view of the machine, in operative posItion.

The main frame of the device includes longitudinal metallic members 11 and 12 ter minating in handles 13, the elements 11 and 12 being connected by transverse braces 15.

A U-shaped frame, or yoke 16, is bolted 1U to the lower end of the frame and the lower corners of the element 16 carry rollers 17, 18 for contact with the roof boards.

A transverse shaft 19 mounts a saw 20, say-fourteen inches in diameter, and this shaft is driven by a shaft 21 of a motor 22,through gear wheels 23, 24.

In the present instance, a compressed air motor, supplied with air under pressure by a hose 25, is employed. A duct 26 connected 50 with the hose 25 extends to a point ad- `iacent to the saw, in order to permit of the removal of the sawdust by an air jet.

As above stated, the machine is used by propelling it along the roof at a slight distance from the` edge, the saw being outside of the frame and cutting the boards beyond the path of travel of the machine. The boards are therefore cut at the eaves with a very great saving of time compared with the means usually employed.

lVhat is claimed is In a sawing machine, a main frame including longitudinal and transverse elements, a. second frame, of U form, having its central portion connected with one end of the frame first named, a shaft passing trans versely through the side elements of the U frame, a saw mounted on the shaft and positioned beyond the side elements ol' both 70 frames, a motor mounted on the main frame and including a shaft. extending through the central portion of the U frame and gearing for drlving the transverse shaft from the shaft of the motor, said gearing being within the second frame, of U form.

In testimony whereof I aliix my signature.

WILLIAM E. GERLACH.
